Saving Energy: Storing Data with Topological Magnets

Jülich, 17 November 2017 – Storing, reading, and writing information quickly, using as little energy as possible, and densely on a tiny space are basic requirements for present-day and future information storage devices. Magnetic materials, as employed in billions of hard drives, are extensively tested information carriers. Physicists from Forschungszentrum Jülich have now shown that the magnetic orientation in certain insulators can be controlled even better with the aid of electric fields.

Rydberg Excitons in Cuprous Oxide:
Excitants determine the optical properties of semiconductors and insulators. Their description as hydrogen atom-like complexes has turned out to be an extremely successful concept.
